    Description

      'collidingmice' project from qt sources (examples/qgraphicsview/collidingmice) has been used for testing. It looks like performance on Mac 10.9 is much worse then on previous version of Mac 10.8. Mice move much slower even though processor usage seems to be similar. Only one Mac's process called WindowServer jumps up in usage from 2% to about 22% of CPU where on Mac 10.6 there is almost no difference.

      Attached sampling of collidingmice on 10.8.5 and 10.9.
